Glass in directlight

hi, wonder if you could not delete the AO glass, because the glass at first does not generate a shadow.
This would enable to expand the use of AO inanimations projects, where the pathtracing is still very slow.

The issue here is that rays that pass through the glass, if the area behind it is ocluded, cannot find any indirect light as they are locked inside the object behind it.
This requires a few major changes to the kernel that will make it quite slow, and might make the directlighting kernel much slower for what it was meant for, previewing fast.

Maybe we will add this in the future, or as a specialized kernel for animations.

Specialized kernel for animations *drools*
Where do I pay for the next development stage? :D

Having light passing through transparent objects with direct lighting would be very, very useful.
Very often there are only a few minutes for rendering left and path tracing is nice but still takes some time.
Please add this feature / option. Its useful not only for animations.

+100 :)
maybe an "AO-off" node to put between a node material and the mash-node :roll:
